9/10 times if you flip-flop, the way it is communicated is not with that level of nuance. So you can absolutely change your mind the correct way with given data, and the way it's communicated is with a headline that says "CDC/WHO FLIP FLOPS ABOUT VIRUS". You don't get to decide how people respond to a flip-flop, so you're strongly incentivized to make them as quiet as possible because it's not valued in our society to learn from your mistakes. We just want people who were correct the first time. If you pick a stock, and it goes up you claim you know something about it. If you pick a stock and it goes down and then up, you still point to the stock that you got correct the first time. Also, if you read the article, it's not that they didn't think it was airborne. It was that they didn't believe in airborne viruses. The common wisdom was that viruses are too heavy to stay airborne long enough for them to think it possible to become sick from that.
